CVE-2026-43319

CVE-2026-43319 affects the Linux kernel spidev driver. The vulnerability stemmed from inverted lock ordering between spi_lock and buf_lock across code paths (write/read use buf_lock then spi_lock; ioctl uses spi_lock then buf_lock), enabling potential deadlocks in multi-threaded access. The fix u...
